Besides looking and feeling great, why is maintaining a healthy weight so important? As multiple scientific studies report, maintaining a healthy weight can help you prevent and control many diseases and unwanted health-related conditions. Carrying extra weight puts you at an increased risk of developing life-threatening conditions, such as heart disease, type 2 diabetes, breathing problems, and some cancers. This is the main reason your doctors will continue to stress the importance of maintaining a healthy weight. Of course, reducing risk of disease is just one reason to manage a healthy weight—without excess weight, you will look better, feel better and enjoy more boundless energy to appreciate life.
